THlLL-COUPLING.

EPECIFICA'I'ION forming part; of Letters Patent No. 299,460, dated May27, 1884.

' Application filed February 23, 1884. (N0 modcli To aZZ whom it mayconcern.-

Be it known that I, EDWIN S. BUZBY, a citizen of the United States,residing at Bordentown, in the county of Burlington and State of NewJersey, have invented a new and useful Thill-Ooupling, of which thefollowing is a specification, reference being had to the accompanyingdrawings.

This invention relates to thill-couplings; and it has for its object toprovide a device which will be simple, durable, and efficientin itscharacter, the adjustment of the thills being effected with ease andrapidity.

A further object of the invention is to provide a device in which therewill be no nuts to lose, and which will prevent the noisy rattling ofthe thills; and a still further object of the invention is to provide adevice which will prevent the admission of dirt and gravel to thebearings, and thus add' to the efficiency of the device.

With these objects in view the said invention consists in certaindetails of construction and combination of parts, as hereinafter setforth, and particularly pointed out in the claim.

In the accompanying drawings, Figure 1 is a plan view of my improvedthill-coupling. Fig. 2 is a longitudinal sectional view of the same.Fig. 3 is a perspective view of the parts detached. Fig. 4 is atransverse sectional view on the line 00 00, Fig. 1.

Like letters refer to corresponding parts in the several figures.

Referring to the drawings, A designates the axle, and B designates aclip by means of which the thill-coupler is secured to the axle. Asshown, the base-plate O of the thill-coupler is recessed to receive theaxle, and thus provide a firm connection therewith.

D designates the draw bar or iron, formed integral with the base-plateO, and arranged forward of the axle, said draw-bar being provided with acentral transverse perforation, E, to receive the trunnion F of thethill-iron G, the upper portion of the draw-bar being cut away above theperforation E to form a recess, H, and an opening, I, said openingextending outward from the recess at one side of the draw-bar, as shownclearly in Fig. 3 of the end of the thill, and comprising a circularcap, N, secured to one of the trunnions, and a convex guard, O,projecting inward from the cap, and formed with a slot, P, to enable itto fit around the end of the thill-iron, the cap and guard being formedin one piece of any suitable metal, and adapted to prevent the admissionof dirt or other foreign substances to the bearings of the thill.

The operation of my invention will be readily understood from theforegoing description, taken in connection with the drawings heretoannexed.

To apply the thill, the latter is raised until its end coincides withthe opening I in one side of the draw-bar D, one of the trunnions Fbeing inserted into the perforation E, and the opening I permitting thepassage of the thill inward to its proper position. As seen, the recessH receives the thill, and enables it to drop downward into the usualposition, the trunnions F working in the perforations E, while themetallic sheathing L covers the parts, and thereby prevents theadmission of dirt or other foreign substances, which is a veryobjectionable feature in most thill-couplings. As seen, the rubbercushion in the rear of the thill-iron comes in contact with the same andeffectually prevents the rattling of the thill.

My improved thill coupling is simple, durable, inexpensive, andefficient, and can be readily uncoupled by elevating the thills untilthey coincide with the openings I, when, by drawing the thills outwardfrom one side of the draw-bar, they are uncoupled and can be applied tothe vehicle, as desired.

It will be seen that I do not employ nuts or bolts to hold the parts inthe adjusted position, and for this reason the thill-coupling willalways be held securely and without any dan= ger of working out oforder.

Having described my invention, I claim as In testimony that I claim theforegoing as new and desire to secure by Letters Iatent my own I havehereto aflixed mysignatnre in In a thin-coupling, the combination, withpresence oftwo Witnesses. the draw bar or iron, of the thili fittedtherein,
